ABSTRACT In the field of medieval cartography, the Psalter World Map (BL, Add. MS 28681, fol. 9r) has come to stand in scholarship as an exemplar of the medieval world view. While the World Map has received wide attention, its relationship to the List Map on the verso and the psalter manuscript as a whole has been less discussed. A close material analysis of folio 9 reveals that the two maps were pasted into a frame which had been cut out of the folio. Thus, the maps were constructed separately from the psalter text itself. Moreover, a codicological examination of the first ten folios of the manuscript shows multiple moments of rearrangement and intervention, reinforcing the importance of material analysis in the study of maps and manuscripts. The new information concerning the insertion of the World Map and the List Map into folio 9 opens up unexplored possibilities regarding their place of origin and dating since they can no longer be tied to the 1262 date of the manuscript.

重构世界：BL 中两个 Mappaemundi 的重要性，添加。女士 28681

摘要 在中世纪制图领域，诗篇世界地图（BL, Add. MS 28681, fol. 9r）已成为学术界的中世纪世界观典范。虽然世界地图受到了广泛的关注，但它与背面的列表地图和整个圣咏手稿的关系却鲜有讨论。对作品集 9 的仔细材料分析表明，这两张地图粘贴到了从作品集剪下的框架中。因此，地图是与诗篇文本本身分开构建的。此外，对手稿前十对开页的编纂学检查显示了多个重新排列和干预的时刻，加强了材料分析在地图和手稿研究中的重要性。
